The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
The world's oceans are turning acidic at what could be the fastest pace of any time in the past 300 million years, even more rapidly than during a monster emission of planet-warming carbon 56 million years ago, scientists said on Thursday. Looking back at this bygone warm period in Earth's …
The Power and Energy Ministry is to use Nuclear and Radio Isotope (NRI) technology for sea water pollution management for the first time as sea water contamination has gone out of control in the seas surrounding Sri Lanka, a Ministry spokesman said. He said a workshop on sea water management …
The World Bank announced on Friday a global alliance to better manage and protect the world's oceans, which are under threat from over-fishing, pollution and climate change. Oceans are the lifeblood of the planet and the global economy, World Bank President Robert Zoellick told a conference on ocean conservation in …
U.S. scientists using satellite data have established a more accurate figure of the amount of annual sea level rise from melting glaciers and ice caps which should aid studies on how quickly coastal areas may flood as global warming gathers pace. John Wahr of the University of Colorado in Boulder …
This summary of the fifth Global Environment Outlook report released by UNEP focuses on deteriorating state of the global environment and lists priority areas for action and policy recommendations. The UNEP has released the Global Environment Outlook-5 (GEO-5) Summary for Policy Makers, which was negotiated and endorsed by governments on …
Healthy seas and coasts would pay healthy dividends in a green economy, according to a report released by the United Nations Environment Programme (UNEP) and partners that highlights the huge potential for economic growth and poverty eradication from well-managed marine sectors. The report, Green Economy in a Blue World, argues …
Since the beginning of the Industrial Revolution humans have released ~500 billion metric tons of carbon to the atmosphere through fossil-fuel burning, cement production and land-use changes. About 30% has been taken up by the oceans. The oceanic uptake of carbon dioxide leads to changes in marine carbonate chemistry resulting …
A "very severe" cyclonic storm lay centered about 250 km off Chennai, with the weather office forecasting winds touching up to 135 kph and advising fishermen against venturing into sea for the next two days. "The very severe cyclonic storm 'Thane' over southwest Bay of Bengal moved west-southwestward and lay …
More than twenty years ago, a biological regulation of climate was proposed whereby emissions of dimethyl sulphide from oceanic phytoplankton resulted in the formation of aerosol particles that acted as cloud condensation nuclei in the marine boundary layer. In this hypothesis—referred to as CLAW—the increase in cloud condensation nuclei led …
Marine fisheries are very important to the economy and well-being of coastal communities. Maintaining the long-term prosperity and sustainability of marine fisheries is not only of political and social significance but also of economic and ecological importance. This review presents an updated assessment of the current status of the world’s …
A huge body of water as big as North America’s Great Lakes may lie beneath Jupiter’s moon Europa, astronomers have said. The water body, believed to be locked within Europa’s icy outer shell a few kilometres from the surface, offered one of the best hopes yet of finding life beyond …
The world has made lacklustre progress in meeting most of the commitments it made 20 years ago to safeguard the oceans, says a report. At the 1992 Earth Summit in Rio de Janeiro, Brazil, agreements were made on issues such as sustainable fisheries and aquaculture, capacity building, and biodiversity; later, …
Synoptic weather observations from ships throughout the World Ocean have been analyzed to produce a climatology of total cloud cover and the amounts of nine cloud types. About 54 million observations contributed to the climatology, which now covers 55 years from 1954 to 2008. In this work, interannual variations of …
This document contains the presentation by Swapnil G Sanmukh et al, National Environmental Engineering Research Institute (NEERI), Nagpur on “The phage-host interaction as a model for studying carbon regulation in aquatic system” during Second National Research Conference on Climate Change, organized by the Centre for Science and Environment, IIT Delhi …
Rising CO2 concentrations and water temperatures this century are likely to have transformative effects on many coastal marine organisms. Here, we compared the responses of two life history stages (larval, juvenile) of three species of calcifying bivalves (Mercenaria mercenaria, Crassostrea virginica, and Argopecten irradians) to temperatures (24 and 28°C) and …
The effect of ocean acidification conditions has been investigated in cultures of the diatom Thalassiosira pseudonana CCMP1335. Expected end-of-the-century pCO2 (aq) concentrations of 760 µatm (equivalent to pH 7.8) were compared with present-day condition (380 µatm CO2, pH 8.1). Batch culture pH changed rapidly because of CO2 (aq) assimilation and …
The tiny phytoplankton Emiliania huxleyi, invisible to the naked eye, plays an outsized role in drawing carbon from the atmosphere and sequestering it deep in the seas. But this role may change as ocean water becomes warmer and more acidic, according to a San Francisco State University research team. In …
Notwithstanding China’s objections, India is expected to further intensify its cooperation with Vietnam in the hydrocarbon sector. The issue is likely to figure prominently during talks between Vietnam President Truong Tan Sang and Prime Minister Manmohan Singh here on Wednesday. Indian officials said the Gas Authority of India Ltd (GAIL) …
An ambitious mission to search for life that has been buried beneath 3km of ice in an Antarctic lake for hundreds of thousands of years begins in earnest this week. A team of British scientists and engineers will start transporting the 70 tonnes of drilling equipment needed to penetrate the …
A study using the Herschel space telescope aimed to measure the fraction of deuterium, a rare type of hydrogen, present in the comet’s water. Like our oceans, it had half the amount of deuterium seen from other comets. The result, published in Nature, hints at the idea that much of …
